Product Description:

The MAC090B-0-PD-4-C/130-A-0/WI522LX/S03 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for use with analog drives where precise electromechanical conversion is needed to position tooling, transport loads, or synchronize machine axes within automated production lines. The motor fits the 090 frame class and integrates speed-sensing hardware so that legacy drive amplifiers can regulate velocity without external transducers.

The centering diameter of 130 mm establishes a fixed mechanical datum between the motor flange and the driven machine member. Heat generated in the stator is dissipated by natural convection; no auxiliary blower or liquid circuit is required when ambient airflow is available. Under nominal operating conditions, the shaft reaches 1500 rpm, a speed suitable for medium-inertia indexing tasks common in packaging or material-handling stations. Power conductors exit through a connector on side A, allowing straightforward cable routing that follows the standard MAC layout. For continuous speed verification, the internal tachogenerator outputs 3 V/1000 rpm, supplying the drive electronics with a linear voltage proportional to instantaneous speed.

The position loop is closed by an incremental encoder mounted in the standard rear housing, delivering pulse trains directly to the control card for fine motion interpolation. Winding code PD aligns the torque constants and rated current with the 090 construction so compatible drives can operate without derating. The unit is supplied without a blocking brake, so applications that need static holding must rely on external clamping or drive torque. Feedback durability is rated as standard tacho quality, supporting consistent analog voltage output over the service life.
